Scope interior trephine device special for spinal endoscope large channel system

Abstract

The invention provides a scope interior trephine device special for a spinal endoscope large channel system. The scope interior trephine device comprises a hollow device integrally formed by a handlepart, a body part and a tail part, and a hollow part of the hollow device penetrates through the handle part, the body part and the tail part; and the handle part is of a T-shaped structure, the bodypart is of a cylindrical structure, and the tail part is of a curved-knife-tooth-shaped structure. The device is used for solving the problems of cutting off and lining of a lower vertebral plate of the large channel system, dependence on an under-scope abrasion drill and a vertebral plate bone rongeur is avoided, the surgery efficiency can be greatly improved, the device has important value in the depressurizing process of serious vertebral canal stenosis, meanwhile taken-out sclerotin can be directly applied to intervertebral space bone grafting, the efficiency of under-scope fusion with percutaneous endoscopic assistance can be effectively improved, and the safety of surgery is improved greatly.

Description

technical field [0001] The invention belongs to the field of spinal minimally invasive technology, and relates to a percutaneous spinal endoscope translaminar approach decompression technique, in particular to an endoscopic trephine device dedicated to the large channel system of the spinal endoscope. Background technique [0002] Spinal endoscopic large-channel surgery system is one of the most popular spinal minimally invasive techniques at present. In addition to being widely used to solve various complex lumbar disc herniations, it is also gradually applied to the treatment of severe lumbar spinal stenosis and cervical spondylosis. Currently, percutaneous Endoscopic-assisted fusion technology is also gradually being respected, but how to improve the operation efficiency and achieve sufficient decompression is the key link affecting the promotion of this technology. The large channel system has a thicker inner diameter than conventional endoscopes, and can use larger endo...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide an endoscopic trephine device dedicated to the large channel system of the spinal endoscope, which is used to solve the problem of decompression of the spinal canal of the large channel system. After the large channel is placed, the device can be put into the device under direct vision , and then gradually remove the lamina bone for lamina alignment and decompression. The unique depth-limiting device can achieve precise and safe decompression, and the efficiency is much higher than that of grinding drills and lamina rongeurs under the microscope, which greatly improves the safety of the operation. sex
